The correct IUPAC name of the following compound is :
To determine the IUPAC name of the given compound, follow these systematic steps:
- Identify the longest carbon chain in the compound. The main chain should have the maximum number of carbon atoms. In the given structure, the longest chain consists of 7 carbon atoms.
- This chain is a heptane backbone.
- Identify and number the substituents (alkyl groups). Number the chain in such a way that the substituents get the lowest possible numbers.
- The numbering starts from the end nearest to the first substitute: the third carbon has an ethyl group, and the fifth carbon has a methyl group.
- Combine the information to name the compound. Arrange the substituents in alphabetical order, and join them with the main chain name.
- The correct name is 3-ethyl-5-methylheptane.
Thus, the IUPAC name of the compound is 3-ethyl-5-methylheptane, which matches the correct answer option provided.
